Archaebacteria: Individual archaebacterium is 0. Eubacteria: Individual eubacterium is 0. Archaebacteria: Archaebacteria are spheres, rods, plates, spiral, flat or square-shaped. Eubacteria: Eubacteria are cocci, bacilli, vibrio, rods, filaments or spirochetes in shape.
Archaebacteria: Archaebacteria are simple in their organization. Eubacteria: Eubacteria are more complex than archaebacteria. Archaebacteria: Archaebacteria are found in extreme environments.
Eubacteria: Eubacteria are found everywhere on earth. Archaebacteria: Cell wall is composed of pseudo peptidoglycans. Eubacteria: Cell wall is composed of peptidoglycans with muramic acid. Archaebacteria: Membrane lipids of archaebacteria is ether-linked, branched, aliphatic chains, containing D-glycerol phosphate.
Eubacteria: Membrane lipids of eubacteria are ester-linked, straight chains of fatty acids, containing L-glycerol phosphates. Archaebacteria: RNA polymerase of archaebacteria consists of a complex subunit pattern, which is similar to eukaryotic RNA polymerase. Eubacteria: RNA polymerase of eubacteria consists of a simple subunit pattern.
Archaebacteria: Introns are present in archaebacteria. Eubacteria: Introns are absent in eubacteria. Archaebacteria: Asexual reproduction methods like binary fission, budding and fragmentation are used by archaebacteria during their reproduction.
Eubacteria: Other than binary fission, budding and fragmentation, eubacteria are capable of producing spores in order to remain dormant during unfavorable conditions. Archaebacteria: Archaebacteria are three types: methanogens, halophiles and thermophiles. Eubacteria: Eubacteria are two types: gram positive and gram negative.
Archaebacteriapossess some unique characteristic features, which make them differ from eubacteria. Among these differences, the most noticeable are the cell wall composition. Unlike in eubacteria, archaebacteria do not contain muramic acid and D-amino acids in peptidoglycan.
Their cell wall is composed of proteins, glycoproteins or polysaccharides. A few genera of archaebacteria possess cell wall made up of pseudomuerin, which has the same structure of eubacterial peptidoglycan, but still differs in chemical composition. Eubacteria are phototrophic, chemotrophic or heterotrophic organisms that show a wide range of metabolic activities. They are present in almost everything, soil, the river, the ocean even the human feces. The varieties of bacteria are available on this earth.
Some are harmful to humans and some are brilliantly useful too. The categories of bacteria are scientifically based on the nature of their cell walls and shapes. Few are categorized based on genetic makeup as well.
One is the Archaea and the other is the Eubacteria. The difference between the Archaea and Eubacteria is that Archaea is a single-celled bacterium that thrives in extreme conditions while eubacteria live and thrive in normal conditions.
Archaea is the oldest bacteria ever known while the earth was formed. Archaea are single-celled and simple microorganisms that live and thrive in extreme conditions. They are extensively found in places like deep ocean bed, salt brine and also in volcanic eruption sites. They belong to the Monera Kingdom and they are prokaryotes. Archaea are also commonly called as extremophiles.
Archaea are of different shapes. A few are flat and square-shaped while many are in the shapes of spirals, rods, plates, and spheres. The cell wall of archaea is made of pseudopeptidoglycan. Archaea have been observed to have lipids linked with ether with the branching of aliphatic acid. The reproduction process of Archaea is carried out Asexually. Both of them are unicellular microorganisms and are commonly called prokaryotes.
The difference between eubacteria and archaebacteria is their habitat and other characteristics that are specific to them. Eubacteria can live in areas like soil, water, and inside or on some other organisms. At the same time, archaebacteria live in places with extreme environmental conditions. Archaebacteria have various characteristics that differentiate them from eubacteria like their cell membrane chemistry, unique gene transcription, etc.
They lack a membrane-bound nucleus, and their cell wall is made up of peptidoglycans in a cross-linked chain pattern.
This structure helps them to maintain their shape and size. There are generally three types of eubacteria. They have various characteristics. They are generally found in ocean depths.
They are capable of surviving in extreme environmental conditions. Archaebacteria are considered to be the modern form of some of the oldest bacteria found on earth.
